3. (A) is true, but (R) is false.
4. Both (A) and (R) are false.
a. Presence of sound producing vocal sacs
b. Presence of copulatory pad on the first digit of the forelimbs
c. Ureters carry both sperms and urine in male frog
d. Testes are adhered to the upper part of kidneys by a double fold of peritoneum called mesorchium
1. a , b, c and d
2. a and b only
3. a , b and c only
4. c and d only
Bidder’s canals is/are present in
1. Male frog
2. Both male and female frog
3. Female cockroach
4. Bone of mammals
The following diagram shows the male reproductive system of a frog. A, B, C, D and E are respectively:
1. Fat body, Testes, Kidney, Cloaca, Urinary bladder
2. Fat body, Testes, Kidney, Urinary bladder, Cloaca
3. Fat body, Testes, Adrenal, Cloaca, Urinary bladder
4. Fat body, Testes, Adrenal, Urinary bladder, Cloaca
Regarding reproductive system of a male frog:
I. Testes are adhered to the upper part of the kidneys by a double fold of peritoneum called mesorchium.
II. Vasa efferentia are 50 to 60 in number and enter kidneys on their side
III. Vasa efferentia open into the bidder's canal which finally communicates with urogenital duct.
1. I, II, III are correct
2. I and II are correct
3. I and lll are correct
4. II and III are correct
Male and female frogs are distinguishable externally only during breeding season when:
1. the female develops nuptial pad in the thumb
2. the male develops nuptial pad in the thumb
3. the male develops nuptial pad in the thumb and the female develops a nuptial pad on other digits
4. the male develops large nuptial pad in the thumb while the female develops small nuptial pad in the thumb
Select the correct route for the passage of sperms in male frogs:
| 1. | Testes → Vasa efferentia → Kidney → Seminal Vesicle → Urinogenital duct → Cloaca |
| 2. | Testes → Vasa efferentia → Bidder's canal → Uretar → Cloaca |
| 3. | Testes → Vasa efferentia → Kidney → Bidder's canal → Urinogenital duct → Cloaca |
| 4. | Testes → Bidder's canal→ Kidney→ Vasa efferentia → Urinogenital duct→ Cloaca |
